Bio:Pinky Pinkerton was an English member of the original Howling Commandos who fought alongside the team during World War II. Percival Pinkerton was a British Army commando and gentleman ranker who used an umbrella as a weapon along with his Thompson sub machine gun. Pinkerton had served alongside the unit commander Captain Samuel Happy Sam Sawyer prior to Pearl Harbour when both were with the British Commandos. Pinkerton wore Essex Regiment shoulder flashes.

Though never explained in the series, Pinkerton wore a Carlist Requetés type red beret with a yellow tassel with his battledress that may have involved service in the Spanish Civil War. Along with Cpl Timothy Dum Dum Dugan and Dino Manelli, he helped organize the Deadly Dozen (comics).

In issue #23 ("The Man Who Failed") of Sgt. Fury and his Howling Commandos, Percy’s older brother, Lieutenant Colonel Pinkerton appeared. In an issue set in Burma revealed that Pinkerton came from an English family with a long tradition of service as officers to the Crown. Why Pinkerton never accepted a commission was explained as his living a playboy womanising life style during his initial military training that led him to be unable to catch up with his studies and resigining.[1].

In the first Sgt Fury Annual taking place with the Howlers (Howling Commandos) being called back to service in the Korean War, Pinkerton was a sergeant as were all the other former private soldiers of the unit. At the time of their 1966 Vietnam War mission (Annual #3, Sgt Fury and his Howling Commandos) Pinkerton was managing a Playboy Club in London.

As with several other of the Howling Commandos, Pinkerton joined S.H.I.E.L.D..

Notes:He died a year before Secret Warriors 17 was released, according to Dum Dum Dugan.
